A scalable graphene-based membrane

Synthesis of Graphene and Graphene-Based Composite Membrane

Scalable Grid-Based Implementation for Membrane Computing

We first present the formal semantics of a parallel rule-based formalism inspired by biological cells, and then provide a faithful parallel implementation of this computational model by using GridGain and taking care of various synchronization issues. Synchronization is achieved by using barriers and preconditions; both refer to the fact that a membrane can apply its rules only after it has rec...

Graphene as a subnanometre trans-electrode membrane

Isolated, atomically thin conducting membranes of graphite, called graphene, have recently been the subject of intense research with the hope that practical applications in fields ranging from electronics to energy science will emerge1. Here, we show that when immersed in ionic solution, a layer of graphene becomes a new electrochemical structure we call a trans-electrode. The transelectrode's ...

Graphene as a prototype crystalline membrane.

The understanding of the structural and thermal properties of membranes, low-dimensional flexible systems in a space of higher dimension, is pursued in many fields from string theory to chemistry and biology. The case of a two-dimensional (2D) membrane in three dimensions is the relevant one for dealing with real materials. Traditionally, membranes are primarily discussed in the context of biol...

Towards scalable nano-engineering of graphene

By merging bottom-up and top-down strategies we tailor graphene's electronic properties within nanometer accuracy, which opens up the possibility to design optical and plasmonic circuitries at will. In a first step, graphene electronic properties are macroscopically modified exploiting the periodic potential generated by the self assembly of metal cluster superlattices on a graphene/Ir(111) sur...
